基于MATLAB的图像增强技术分析

摘要

为了提高图像的视觉效果,需要对图像进行图像增强处理.由于传统的图像增强方法存在诸多缺点,所以找到一种更好的图像增强算法是目前提高图像处理效果的关键.针对此问题,文中提出一种基于小波分析的图像增强技术,该技术利用小波分析的时频局部化特性与多分辨力的能力对图像进行增强,弥补了传统图像增强算法的缺陷.最后,文中将传统图像增强方法与基于小波分析的图像增强方法进行简要的分析与比较.%In order to improve the visual effect of the image, the image should be enhanced.Because the traditional image enhancement method has many shortcomings, so it is the key to improve the image processing effect to find a better image enhancement algorithm.To solve this problem, this paper proposes an image enhancement technology based on wavelet analysis,the technique uses the ability of time-frequency localization and multi resolution of wavelet analysis to enhance image,and it makes up for the defects of traditional image enhancement algorithms.Finally, the traditional image enhancement methods and image enhancement methods based on wavelet analysis are briefly analyzed and compared in this paper.
